hypoxia
no actually it isnt. the person has still regular amounts of oxygen just more co2. with a mask it can cause this sort of effect moreso than hypoxia i can see.
The issue is, co2 stays in the mask and the mask restricts respiration. Which is why o2 levels fall. Normal o2 levels remain outside the mask. The mask also limits normal respiratory exchange requiring slightly longer breathing cycles to obtain normal function. Are people doing this? The result is a build up of co2 and reduced o2 levels. Classic hypoxia scenario.
This is why I am curious to see people measured with a pulseox to see what's actually walking around.
ok yes but the person breathes haevyer and deeper so they obtain the same amount of oxygen they just need to breathe harder to achieve it. and then what is left is higher amounts of co2 within their breathing-air.
they still get the oxygen after working for it but it doesn't reduce the co2 to non-mask levels.
maybe you didnt read what i said about carbogen. it has drug effects with 5%co2 mixed with 95% oxygen.
under a mask im sure a person could get wafts of co2 that would cause a greater responce than the 'hypoxia discussion'
